Can´t compile C++ GuruxDLMSClientExample using make

Hi, i just download the latest git hub repository and try to compile the example provided but it failed.

When i run *make* it complains about the /bin and /obj folders. I manually create it. Then when i repeat the *make* it shows:

Compiled src/GuruxDLMSClientExample.cpp successfully!
usr/bin/ld: cannot find -lgurux_dlms_cpp: No such file or directory
collect2: error: ld returned 1 exit status
make: *** [makefile:27: bin/gurux.dlms.client.bin] Error 1

I am using g++

Using built-in specs.
